    FAQs: Diamond Necklace Guide

    What makes this diamond necklace different from others?

    What truly sets this diamond necklace apart is the exceptional attention to detail and high-grade materials. Made with 34 round brilliant-cut natural diamonds totalling 0.43 carats, each gem is meticulously selected for F colour and VS clarity. Unlike many mass-produced pieces, this necklace is handcrafted in Sydney using solid 18kt yellow gold, ensuring it’s not only beautiful but durable enough to become a family heirloom. It’s that sweet spot where everyday elegance meets investment-worthy quality.

    Can I wear this necklace every day?

    Absolutely! Designed for versatility, this diamond necklace is light enough for daily wear yet striking enough to elevate your look for special occasions. The 18kt yellow gold adds both strength and luxury, while the secure setting keeps your diamonds safe. Furthermore, it layers beautifully with other fine necklaces too, so it adapts effortlessly from casual to chic. Just remember to remove it when swimming or showering to keep it gleaming.

    Is this necklace a good gift option?

    This piece is a brilliant gift—whether it’s for a milestone birthday, a romantic anniversary, or simply celebrating yourself. Its timeless design suits all ages and styles, and its quality speaks volumes about the thought behind the gift. Plus, it comes beautifully packaged, and you can even book a private appointment to hand-select matching items.

    How do I care for my diamond necklace?

    Keeping your necklace in top condition is simple. Wipe it gently with a soft lint-free cloth after each wear to remove oils and dust. For a deeper clean, soak in warm water with mild dish soap and gently brush with a soft toothbrush. Additionally, avoid harsh chemicals and always store it in its jewellery box or pouch to prevent scratches. Regular professional cleans can also keep it looking its absolute best.

    Can I customise this necklace or create a matching set?

    Yes! At Ernesto Buono, we love creating bespoke jewellery. Whether you want to tweak the diamond count, change the gold colour, or design a matching bracelet or earrings, our expert jewellers are here to bring your vision to life. Just book an appointment and we’ll guide you through your options.

    How do I know the diamonds are ethically sourced and authentic?

    Every diamond used by Ernesto Buono is ethically sourced and either GIA-certified natural or top-quality lab-grown, depending on your preference. This particular necklace features natural diamonds of F colour and VS clarity—each verified for quality. You’ll receive all documentation with your purchase, so you can feel confident in both beauty and integrity.
